3.2.2 Welding preparations
 Pipes smaller than the maximum welding range (diameter) of the machine, mount the
adapter clamping inserts suited for the pipe diameter with the Allen screws found in the
accessories kit.
ROWELD P200B: Ø63-140mm: consisting of six wide-surface shells and two small-surface
shells. Ø160-180mm: consisting of 8 wide-surface shells.
ROWELD P160-355/5-12B: consisting of six wide-surface shells and two small-surface shells.
ROWELD P500-630/18-24B Plus: consisting of six wide-surface shells and two small-surface
shells (for diameters up to 450 mm) or 8 wide-surface shells (for diameters >500 mm).
In so doing, please observe that the small-surface shells are mounted to the two lower
external main clamps. These are used in the left basic clamping element below and above
only for pipe to pipe bend connections.
 Insert the plastic pipe or fitting in the clamping device (use dolly with longer pipe < 2,5m
sections) and tighten brass nut on the upper clamps. Adjust brass nuts (tighten or loosen) to
compensate for any ovalness.
For P200B:
 The machine is operated with 4 basic clamping jaws in the case of
pipes / pipe connections (welding position A).
 The 4th basic clamping jaw can be removed in the case of narrow
pipes / fitting connections (welding position B). To do this,
initially remove the screws (3) and then slightly loosen the screws
(5). The 4th jaw can now be pulled out together with the sub-
construction. Finally, unscrew the spacers (4) and replace them by
the screws (3).
 For pipe-to-pipe connections, the two spacers must be
engaged in both left clamping elements (standard
configuration at delivery).
Attention: Under no circumstances should the spacers be
installed diagonally offset!
The pipes are each held by two clamping elements.
Pipe / Fitting P160/5B:
 For pipe-to-fitting connections, the two spacers must be
engaged in both middle clamping elements.
Attention: Under no circumstances should the spacers be
installed diagonally offset!
 The pipe is inserted into three clamping elements, and the fitting is held by one
clamping element. Thus, the movable clamping element can be shifted on the rod as space
requirements demand during clamping.
Pipe / Fitting P250-355/8-12B:
 For pipe-to-fitting connections, the two spacers must be
engaged in both middle clamping elements, and the heating
element take-off device is suspended into the left clamping
elements.
Attention: Under no circumstances should the spacers be installed diagonally offset!
 The pipe is inserted into three clamping elements, and the fitting is held by one clamping
element. Thus, the movable clamping element can be shifted on the rod as space
requirements demand during clamping.
